shellscripting

[Rakeshvijayan]

hi friends

I am new in shell scripting ,I wish to know something from your knowledge ..

I wish to add this below commands in sudo gedit /etc/mysql/my.cnf file [Under the Basic settings section, ]
# UTF-8 Defaults for Koha
init-connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_general_ci

how can I do it ? is it possible to do so ?

Thanks

If it is a one time activity you might not need to scriptize it .

echo -e "init-connect='SET NAMES utf8'\ncharacter-set-server=utf8 \ncollation-server=utf8_general_ci" | sudo tee -a /etc/mysql/my.cnf

The above commanline will append the configuration entries to the mentioned mysql conf file .Before making changes to the file dont forget to get a back up .

sudo cp  /etc/mysql/my.cnf  /etc/mysql/my.cnf_orig

Any type of text file manipulation is possible through native Unix utilities .Please post your exact requirement .

In order to do a passwordless ssh , you need to set up public ket authentication .Please follow the below guide .

As said before, use expect to send your credentials. expects interacts as a real user. Read the expect docuemntation and you will be able to make what you want.

Passwords were never meant to be provided in some configuration files for some scripts/programs to be read and get executed .This will deny the 35 years of Unix security .
